AT Commands
:U
n DCD Time Delay
Where n is an integer from 0 to 255 representing periods of 12.5 milliseconds. Default
is 0. During MI/MIC operation, sets how long the modem waits before turning on DCD
(carrier detect).
NOTES
•
The :U command takes effect when :R1 is set. If the DCD signal is already On
before the connection, the modem ignores the :U command.
•
The modem supports this command in Dial Access Security. :R does not need to
be set.
@U
n Minimum Connection Speed
Where n = 300, 600, 1200, 2400, 4800, 7200, 9600, 12000, 14400, V14400, 16800,
19200, 21600, 24000, 26400, 28800, 33600 bps.
Sets the minimum modem port speed for connections. For example, if you want your
modem to only make connections greater than or equal to 4800 bps, set AT@U4800.
The modem will only make connections at 4800 bps or higher.
V
n Result Code Form
V0
Sends short-form result codes.
V1
Sends long-form result codes.
Selects whether the modem sends long-form (words) or short-form (numeric) result
codes to your computer. The format of the connection result codes is dependent upon
the \V, W, and -M commands.
$V
n Logon View Mode
$V0
Disables pass through of data during the logon sequence.
$V1
Enables pass through of data during the logon sequence.
Determines whether data passes through from the remote system to the local computer
during the logon sequence. With view mode disabled ($V0), the modem does not pass
through any data and delays the connect message until the logon sequence is complete.
With view mode enabled ($V1), the connect message displays and then data pass
through during the logon sequence.
%V Display Modem Firmware Version
Displays the modem firmware main code version.
